The two rugged men have built a solid list of BFF accomplishments over the years, including Tweedy’s numerous appearances on Parks and Rec, and more extremely, a love letter from Offerman professing his plans to marry Wilco’s frontman. However, their latest endeavour of writing songs together truly takes the cake.

Offerman recently published Good Clean Fun, a book detailing his “misadventures in sawdust.” Accompanying the audiobook version of it are five original woodworking-themed songs, penned and performed by Offerman and Tweedy: “Music to Sand By,” “American White Oak,” “Raising the Grain,” “The Lazy Carpenter” and the title track, “Good Clean Fun.”
